[QUOTE="Trickymissfit, post: 1151060, member: 25383"] Honestly I had zero idea what a minute of angle meant forty years ago. Yet I'd had trig and calculus. Never totally understood it, and what it meant in the real world. Yes I heard the term arc seconds a few times here and there, but that was about it. In the mid 1980's I was introduced to the term again, but this time I learned to use it. I learned the black art of cutting surface plates to the Fed's lab grade spec. Being able to see a tenth of an arc second show up on an autocollimator made it easier to understand the concept. Otherwise I had no idea what or why. Suddenly one day while laying ontop a cold piece of granite I saw the triangle generated from the bench to the target 100 yards out. Then I started experimenting to see just what I could do with this new found concept in measurement. gary [/QUOTE]
